\code{sr} \tab (data.frame) Selectivity ratio for a variable represents a measure of a variable's importance in the PLS model. The output data.frame contains a column of selectivity ratios, a column of p-values based on an F-distribution and a column indicating significance at p < 0.05. \cr
\code{sr_pvalue} \tab (data.frame) A p-value computed from the Selectivity Ratio based on an F-distribution. \cr
